MAX77301 Lithium-ion Linear Battery Charger Analog Devices MAX77301 Lithium-ion Linear Battery Charger is JEITA-compliant and operates from a USB port, a dedicated charger, or a universal adapter. The IC provides automatic adapter-type detection and enumeration with a USB host or hub. The IC integrates an independent battery charge switch, current sense circuit, MOSFET pass elements, thermal regulation circuitry and eliminates the external reverse-blocking Schottky diode. This feature creates the simplest and smallest USB-compliant charging solution.
